This approach supports me in my work with children/young people and their families. DDP is a really helpful therapy for any family experiencing difficulties in managing their child/children. Children/young people can experience difficulties throughout their early and teenage years which may exhibit as behaviour difficulties, withdrawing and isolation, family conflict and school problems. DDP is based on and brings together attachment theory, what we understand about developmental trauma, the neurobiology of trauma, attachment and caregiving, intersubjectivity theory and child development.
